I'm using customEvent when my sidebar is shrunk or expanded.
When event is dispatched I use .forceRender() method to update grid layout because it overflows in the page, but it doesn't work.

When I reload page, whether the menu is shrunk or expanded, the grid displays and column widths are calculated correctly so it does not overflow.

I don't know what I'm missing here, maybe recalculate column width is not part of forceRender method ?
